This volume contains the proceedings of an international workshop on "Experiences with Distributed Systems" held September 28-30, 1987, at the University of Kaiserslautern. The workshop was jointly sponsored and organized by the Sonderforschungsbereich 124 "VSLI-Entwurfsmethoden und ParallelitAt" and the European Network Center (ENC) of the IBM Corporation, Heidelberg. The objective of the workshop was to bring together researchers who had gathered substantial experience with the implementation of distributed systems. The emphasis was put on the exchange of (good and bad) experiences with existing concepts in distributed system design rather than presenting new ideas. Participation in the workshop was by invitation only. The presentations can be roughly categorized as reports on a specific project or reports on experiences with a certain topic accumulated through several projects. Other lectures treated general topics such as fault tolerance, design principles for distributed languages and systems, and distributed databases.

This volume contains revised versions of presentations at the International Workshop on Analogical and Inductive Inference (AII '86) held in Wendisch-Rietz, GDR, October 16-10, 1986. Inductive inference and analogical reasoning are two basic approaches to learning algorithms. Both allow for exciting problems and promising concepts of invoking deeper mathematical results for considerable advances in intelligent software systems. Hence analogical and inductive inference may be understood as a firm mathematical basis for a large variety of problems in artificial intelligence. While the papers on inductive inference contain technical results and reflect the state of the art of this well-developed mathematical theory, those devoted to analogical reasoning reflect the ongoing process of developing the basic concepts of the approach. The workshop thus contributes significantly to the advancement of this field.

This volume contains the proceedings of the Second International Conference on Rewriting Techniques and Applications, "RTA 87," held in Bordeaux, France, May 1987.

This book is designed for non-computer specialists, especially for executives, ad ministrators and managers who want to make better use of their software specialists and experts. The way this Springer edition has come to be published is itself a story. Back about 1980, the founder and president of one of the more successful microcomputer companies, Mr. Kazue Ishii of CEC, wanted to start somethig that would be brilliant, sophisticated, innovative, and which would grow steadily. Out of many proposals, the one he accepted happened to be mine. The proposal was to build a family of network workstations for computer-aided design/manufacturing and office automation. UNIX was to be used as a software generator. But he had a hard time understanding UNIX, what good it is and how good it is ... Spending a significant amount of time with a popular computer columnist, Miss Yukari Shirota, I compiled this book for him. I found this book generally useful for top executives, managers, planners and office administrators whose background is outside software engineering. Dr.
